This is an activity designed to develop a working definition of life. Learners will conduct a simple experiment, looking for signs of life in three different "soil" samples. The experiment introduces children to the difficulty that scientists face...(View More) in defining life. By observing the soil samples, participants try to determine if any contain signs of life and work to identify, refine, and create a set of characteristics that may be used to identify living versus nonliving things. The activity concludes with the development of a group definition of life. This group definition will be referred to in subsequent activities. It also includes specific tips within each activity for effectively engaging girls in STEM. This is activity 1 in Explore: Life on Mars? that was developed specifically for use in libraries.(View Less)

This is a set of two improv-style activites that encourage participants to participate in learning about living and nonliving things. Learners will get to know each other through an icebreaker activity and state their ideas and previous experience...(View More) with living versus nonliving things. This will help prepare them to explore how scientists define and look for life in worlds beyond our own. It also includes specific tips for effectively engaging girls in STEM. This is the icebreaker activity in Explore: Life on Mars? that was developed specifically for use in libraries.(View Less)

This activity focuses on how the search for life on Mars is portrayed in fiction and videos. Learners will consider depictions of Mars from science fiction books and video clips. As a group, children discuss what they know about Mars and compare...(View More) their ideas with the way Mars and imaginary martians are presented in the science fiction works. They then use what they’ve learned to create their own Mars Science Fiction “Movie Trailer” Zines. It is recommended that this activity is preceded by two or three of the previous activities in the series so that the children will already have an understanding of what life needs and how Mars compares to Earth. This activity may be extended to serve as a tween and/or teen science fiction book club. It also includes specific tips for effectively engaging girls in STEM. This is activity 7 in Explore: Life on Mars? that was developed specifically for use in libraries.(View Less)

This is a lesson about landing site selection. Learners will work in teams to determine a landing site for their Mars Rover that best relates to their scientific question. They use technology skills to research Gale Crater through an online...(View More) interactive module and learn about features of Mars through use of Google Earth Mars. The lesson uses the 5E instructional model and includes: TEKS Details (Texas Standards alignment), Essential Question, Science Notebook, Vocabulary Definitions for Students, Vocabulary Definitions for Teachers, three Vocabulary Cards, and a Mini-Lesson. This is lesson 8 of the Mars Rover Celebration Unit, a six week long curriculum.(View Less)

This is an activity about the Moon's influence on Earth. Learners think like a scientist — with reasoning skills and a healthy amount of skepticism — to sort puzzle pieces containing statements about the Moon into two images. The "Far-out Far...(View More) Side" has incorrect statements about the Moon (urban myths), and "True-Blue Blue Moon" has true facts about the Moon’s influence on Earth and life. This activity is part of Explore! Marvel Moon.(View Less)

Learners create edible models of the interior composition of the Earth and Moon. Common food items are used to construct the cores, mantles, and crusts of both planetary objects. They then compare their structure as they are eating their models....(View More) This activity is part of Explore! Marvel Moon.(View Less)

Learners color images of the latest scientific data depicting the Moon's formation to create their own comic strips of our Moon's birth. The children use different-colored balls of Play-Doh® to model the impact between Earth and a small planet 4.5...(View More) billion years ago. "Debris" from both "planets" is rolled into a small ball to model how our Moon formed through the process of accretion of smaller particles. This activity is part of Explore! Marvel Moon.(View Less)

This is an activity about the history of the Solar System. Learners work in groups to determine the order of geologic events — such as the formation of the Moon and when the bright crater of Tycho formed — and arrange images depicting those...(View More) events in the correct order. The children are introduced to NASA lunar scientists, who are currently investigating the Moon's history, through comic-book style visualizations of their real-life work. Finally, the children share their own histories by drawing, comic-book style, a past connection with the Moon in their own lives. This activity is part of Explore! Marvel Moon.(View Less)

In this activity, students analyze a 2011 article by physicist Dr. Richard Muller addressing the climate change skeptic's claim that the scientific data used to support global warming is poor or unreliable. He headed a two-year study where his...(View More) research team examined sources of data independently of climate scientists, and concluded that despite the imperfections in the available data sets, scientists have managed to avoid bias in data collection and correction. A student worksheet provides questions to guide the investigation. This activity is supported by a textbook chapter, What is Global Warming?, part of the unit, Climate Change, in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.(View Less)

This online, facilitated course is designed for middle-school educators wishing to teach global climate change using an inquiry/problem-based approach. Teachers access the course by registering with PBS TeacherLine and enrolling in the course. The...(View More) course supports teaching global climate change using a problem-solving approach and STEM (science, technology, engineering, and mathematics) methodology to engage middle-school students and help them understand the causes and effects of climate change and learn about the differences between climate and weather and how actions and nature affect the environment. The course includes pedagogic support for educators who are interested in using Web 2.0 tools when teaching about climate change in the classroom. Enhance content knowledge of climate change and learn how to effectively implement STEM instructional strategies using resources from NASA and WGBH’s Teachers’ Domain.(View Less)
